Crash board assembly and self-moving robot

Abstract

The present application provides a striker assembly and a self-moving robot. The striker assembly is fixed to a target object, including: a striker body; a trigger mechanism configured to be displaced into the first stroke when the striker body undergoes a collision , triggering to send a stop motion signal to the target object; the buffer mechanism is configured to perform elastic buffering on the striker body when the striker body is further displaced and enters the second stroke. According to the application, by setting double strokes, the trigger mechanism can be easily triggered in a short stroke when an obstacle is encountered, and timely feedback that the target object stops moving, and then the elastic buffer in the second stroke can effectively slow down the target The inertia after the object stops moving and the impact force brought by the braking distance greatly improve the safety and practicability of the target object. In addition, the controls are simple and efficient to use, and the target object can easily get the job done in collision-prone scenes.

Description

technical field [0001] The present application relates to the technical field of intelligent robots, in particular to a collision plate assembly and a self-moving robot. Background technique [0002] With the development of technology and the rise of labor costs, more and more public places (shopping malls, hotels, office buildings, airports, etc.) are gradually using intelligent cleaning robots to clean the ground. However, because public places require machines to clean a large area at a time, cleaning robots generally weigh more than 30kg when a single fresh water tank is fully loaded, and when the cleaning speed is 0.5m / s, the instantaneous impact force can reach more than 200N, which is very important for smart robots. The safety requirements for the operation of cleaning robots are particularly high. [0003] At present, the strike stroke of intelligent cleaning robots on the market is generally within 10mm, and the ratio K of the rebound force to the stroke of the st...

AI Technical Summary

Problems solved by technology

If the design value of the springback force F of the collision board is smaller, the impact force of the cleaning robot on the obstacle will be minimally buffered after the collision board is triggered; if the design value of the rebound force F of the collision board is larger, the collision board will become difficult to trigger, and some fragile obstacles Objects cannot be effectively protected, even until the collision plate is not triggered, the design value of the rebound force F is difficult to achieve a balance in a single set of elastic devices

In summary, dangerous accidents may occur during the cleaning process of cleaning robots
